The purpose of this study was to investigate the performance and physiological responses to different repeated sprint tests (RST). Nineteen basketball players participated in this study voluntarily. Participants were randomly participated in straight-repeated sprint test (6x25m; SRST), 180° shuttle-repeated sprint test [6x(2x12,5m); SHRST] and 100º change of direction-repeated sprint test [(6x(25m) CODRST] with 25 seconds passive recovery durations. After 3 different RST, best sprint time (BST), total sprint time (TST), and percentage of performance decrement (PD%) were determined as performance responses. Participants' heart rate (HR) was continuously recorded before and during the tests to determine resting, mean and maximum heart rates (HRrest, HRmean and HRmax, respectively). In addition, rest (LArest) and maximal lactate (LAmax) and maximal rate of perceived exertion (RPEmax) responses were determined. Repeated measures of ANOVA indicated statistically significant differences in BST and TST values among 3 different RST (p<0,01). Bonferroni results showed that BST values at SRST were significantly better than the SHRST-BST and CODRST-BST values. On the other hand, SHRST-BST values were significantly better than CODRST-BST values. When TST values were examined, it was seen that SRST-TST values were significantly better than TST values obtained from the other two RST. PD% values on the other hand, were similar (p>0,05). In addition to these findings, there was no significant difference in HRmean, HRmax, LAmax and RPEmax measured during the tests (p>0,05). It can be concluded that, although there was no significant differences in physiological responses, performance responses in SRST were better than the other two tests.

Aim of this study is to determine the energy availability during training season in female aesthetic sports and to examine the prevalance of relative energy deficiency indicators such as low energy availability, low resting metabolic rate, energy deficiency, disordered eating and eating disorders, low bone mineral density, menstrual dysfunction and low body weight. A total of 42 elite female aesthetics athletes (17 aerobic gymnasts, 13 rhytmic gymnasts, 12 figure ice skaters) and 12 non-athlete age controls participated in this study. Age range of the participants were 11-17 years. Resting metabolic rate was measured by indirect calorimetry, body composition and whole body bone mineral density were measured by dual-energy X-ray absorptiometry. Energy intake, energy expenditure, energy availabilty and energy deficiency levels were determined based on the data obtained by 3-day food intake and 3-day physical activity records. In addition; Low Energy Availability in Females Questionaire and the Eating Attitude Test-40 were adminestered. Data was analyzed by using one way ANOVA test. Mean energy availability levels were 34.81±18.13, 19.49±13.79, 16.81±17.04 and 43.31±10.49 kcal/kg FFM/day for aerobic gymnasts, rhytmic gymnasts, figure ice skaters and controls, respectively. Prevalance of low energy availability (≤30 kcal/kg FFM/day) for the same groups was determined as 41%, 85%, 83% and 8%, respectively. Clinicaly meaningful energy deficiency (< -500 kcal/day) was determined %98 in all groups. The highest prevalance of chronic low energy availability markers was observed in rhytmic gymnasts (59% of the participants had 3 or more risk factors). In all groups; water, macronutrients and evaluated mineral consumption were lower according to daily reference intake values. In conclusion, female aesthetic sports athletes, evaluated in this study, have high risks in terms of energy availability. Therefore, it is necessary to monitor the athletes individualy especially during training and competition season and take precautions to ensure that the energy availability is maintaned.

Tuna N. The Effect of Mental Training with Biofeedback on Performance in Athletes. Hacettepe University Graduate School of Health Sciences, M.Sc. Thesis in Sport Sciences and Technology Program, Ankara, 2018. The purpose of this study is to investigate the relationship between neural feedback training and the archers’ performance. After applying all intervention two groups compared in terms of archery performance. Participants (N=30) were in İzmir Metropolitan Municipality Archery Team (18.33±2.41 years) participated in the study. The two groups were divided into two groups as experiment and control considering the view of the coach. All participants were applied to performance test (2x36=72 arrows) attention test and anxiety inventory and EEG baseline measurement. In addition, EEG-Biofeedback data were obtained. A 20-session sensory motor retention activity augmentation session was performed in the experimental group. After a baseline measurement participants are assessed on and at heir performance test (36x2=72 arrows) whether experimentel group have been improved on their archery performance or not. ANOVA (2x2), t-test, normality test and Wilcoxon test was performed in data analysis. There was no statistically significant difference between the groups in terms of performance results, physical anxiety and self-confidence scores of the anxiety (CSAI-2) inventory, teta, beta values of the EEG-BGB record, and subscale scores of the IVA-2 test (p>0.05). It was observed that the shot performance scores of the experimental group were higher than the shooting scores of the control group. In addition, cognitive anxiety of pre-test and post-test groups showed that the cognitive anxiety level were lower in the experimental than control group and there was a significant difference between the pretest post-test interaction of the experimental group in the intragroup analyzes and the [F(1,28)=9.35;p=0.00;p2=0.250], [F(1,28)=4.44;p=0.044;p2=0,137] thus, the athlete could
focus better and ignore the external factor. In addition, it shows that DMR values in the post test of individuals in the experimental group are higher [F (1,28)=6.91;p=0.01;p2=0.198].
Increase in DMR values have shown that archers are able to focus attention, and learn to control their own physiology. In the visual focus subscale of the IVA-2 attention test, there was difference between the measurements and groups intercaction is [F(1,28)=8.79;p=0.006;p2=0.239] A significant difference of between groups indicated
that archers can facilitate focusing skill of the during shooting.

This study was
designed to investigate the physiological and kinematic responses to small-sided
games applied with different size and player numbers in football and futsal players.
The study data were collected from 12 futsal and soccer volunteer players (age:
21.12±3.15 years, height: 175.38 ±5.78 cm, weight: 71.00 ±6.74 kg). Before the small
sided games anthropometric measurements were performed and Yo-Yo 1 field test was
applied to determine players’ maximum heart rate (HRmax) (195.95±6.98 beats.dk-1)
and VO2max (53.22±2.17 ml.kg-1.dk-1). 2 sets of 2x2, 3x3 and 4x4 small-sided games
were played in different time and area sizes. However, the amount of m2 (100 m2) per
player was constant when the playing fields were changed. Average heart rate
(HRaverage), HRmax, lactic acid (LA), ratings of perceived exertion (RPE), total distance
(Distancetotal), maximum speed (Speedmax), average speed (Speedaverage), distance
covered in 5 different speed zones(Speedzone1,Speedzone2,Speedzone3,Speedzone4,
Speedzone5) and average metabolic power (MG) values were calculated during smallsided
games. Differences in age, height, body weight, body fat, training age, and
VO2max of the players were assessed by Independent T-Test. The differences between
physiological and kinematic variables during small sided games were calculated with
two way repeated measures of ANOVA and the level of significance was accepted as
0.05. Results indicated significant differences in physiological variables such as
HRaverage, HRmax, LA and RPE, and kinematic variables like Distancetotal, Speedmax,
Speedaverage, Speedzone1, Speedzone2, Speedzone3, Speedzone4, Speedzone5 and average MG
variables during the games and between football and futsal players (p <0.05). As a
conclusion although no differences were observed in physiological responses during
different small sided games, futsal players were found to have higher kinematic
responses to different small games. In addition during all small sided games
physiological responses during second sets were found to be higher than the first sets.
